GPS Creations offers the GPS SIM14, an L1/L2 GPS constellation simulator available in either C/A code–only or C/A-code and P-code configurations, which can simulate up to 14 satellites simultaneously. The simulator can be integrated with a multi-function feature card (MFI/O) to provide extended capabilities such as IMU, automotive, and factory test & timing. An adjustable RF power output has a dynamic range of 66 dB.

National Instruments offers the NI GPS Toolkit for LabVIEW, an extension of the graphical system design environment that expands the NI RF PXI platform to include multi-satellite GPS signal simulation. Using NI LabVIEW software to create waveforms that simulate up to 12 satellites (C/A codes in the L1 band), engineers can test receiver characteristics such as sensitivity, time to first fix (TTFF) and position accuracy with the NI PXIe-5672 RF vector signal generator.
